Interior door weight. Metal door weight Entrance doors weight

The weight of a metal door depends on the thickness of the metal in the door leaf structure. The rule is simple, more thickness means more mass. Most of the entrance doors profil doors are lightweight, this value ranges from 40 kg. At the same time, there are doors of the middle weight category (this is 60-70 kg), as well as the so-called specialized doors, the weight of which is veiled from 120 kg and more. Let's take a closer look at what makes up the weight of a metal door and what it actually shows. An equally important role in the weight of the door is influenced by the weight of its metal frame. The design feature of the door leaf also contributes. We are talking about the number of stiffeners, the configuration of the frame and the thickness of the steel sheet welded to it.

The front door should weigh exactly as much as its functional purpose requires. This principle is the basis for calculating the weight of metal doors.

Of course, single-leaf metal doors weigh less than double-leaf doors (a door with two leaves). Practically equal in size, the latter are superior in weight to the former due to the complexity of the design, as well as higher requirements for reliability and strength. Do not disregard decorative trim, lining, locks, hinges and other additions, which together also form the weight of the metal door. Insulated metal doors are definitely heavier than conventional doors. However, manufacturers try to keep this difference as low as possible. This goal is achieved with modern insulating materials. Their presence inside the door leaf leads not only to the retention of heat inside the house, but also to the muffling of extraneous noises emanating from outside it. In the center of such a door frame and door leaf there is a volumetric and at the same time negligible weight seal (usually rubber). Wood paneling, plywood and the construction of a double narthex give an equally small add-on.

How much one or another metal door weighs can be found in the accompanying documentation for the product.

How much does a metal door weigh

Based on the above, it turns out that the weight of the metal door block depends on the product configuration. The weight of a simple metal door is much less than doors of the insulated or specialized (the same fire door) type. A significant increase in the weight of the door block can be provided by the installation of an additional metal door grill. At the same time, a door block with one door grill has a lower weight than the same conventional metal front door.

Do not forget that the weight of the door is not so important as the material from which it is made.

How much does a fireproof metal door weigh?

Fireproof metal doors are specialized designs, the functionality of which includes refractoriness and fire resistance. A number of key features affect the weight of a fire door. These include: type of door frame, thickness of door block and steel sheet, characteristics of fire-resistant material, fire-resistance of metal structure. Fireproof metal doors are divided into two types:

1. First generation doorsconsisting of: rectangular pipes in the frame and sheet steel with a thickness of 1.5-2 mm. The average weight of such doors is 50-55 kg / m².
2. Second generation doorsconsisting of: 2 mm thick bent steel profile. The weight of such doors is 40-45 kg / m².

To calculate the weight of a fireproof metal door, the following formula is used: multiply the area of \u200b\u200bthe door block by the weight of a square meter of the door. Door types and their approximate weights:

• Fireproof metal doors of the 1st generation - 55 kg / m²;
• 2nd generation single-leaf doors - 42 kg / m²;
• 2nd generation double-leaf fire doors - 45 kg / m².

Today's market provides the widest selection of metal doors from various manufacturers. But special, far from positive, attention should be paid to metal doors. from a Chinese manufacturer. Most of such products are made from low-quality raw materials and often lend themselves to opening with an ordinary knife. Besides, the weight of such doors is often less than 30 kg, which only increases the likelihood of low quality. All this means that when choosing a door, you need to be very careful about very cheap products. Summing up, we note that the weight of a metal door is not the main indicator of its quality, strength and burglary resistance. Today's manufacturers, on the contrary, strive to increase the safety factor of doors, while gaining in their weight. In addition, the excessive weight of the door structure complicates its operation and leads to early wear of the door hinges.

The weight of an entrance metal door is an important parameter that largely determines most of the characteristics of a product. This is quite logical, given that the most massive parts of the structure are made of steel. First of all, this applies to the box and the canvas, which are the basis of any entrance doors. Therefore, knowing the mass of finished products, it is possible with a high degree of probability to determine how high quality, reliable and durable they are.

Factors affecting the weight of entrance doors

There are several main factors that determine how much the front door weighs. First of all, you should consider the most massive parts and parts of the structure, which form the mass of the product. These include:

• Door leaf and frame. For their manufacture, sheet and profile steel is used. At the same time, the minimum metal thickness, which is established by the GOST standards in force in Russia, is 1.5 mm. Some manufacturers, mainly from China, often use steel sheets with this parameter equal to 1 mm, and sometimes even 0.5-0.7 mm. Obviously, their products are much lighter;
• Reinforcement elements and stiffeners. They are made from shaped metal, and different models contain a different number of similar parts;
• Locking devices and various fittings. In most cases, steel and its alloys with other metals are also used for the production of these components, which are necessarily present in each input structure. As a result, the weight of fittings and locks can be 8 or even 10 kg for some models, which is a significant share in the total weight of the product;
• Finishing and filler. It is difficult to call these parts of the iron door heavy, however, they also make up a significant part of the total mass.

It is especially great when using various decorative forged elements, mirror or glass inserts, as well as when facing the entrance structure with solid wood or MDF panels.

The above factors must first be considered when determining which front door weight is most appropriate. Naturally, the only correct answer to this question does not exist, since it depends on the operating conditions of the product, which can vary significantly.

Standard weight of typical steel doors

Despite the wide variety of steel doors and their different functional purposes, some common points related to the weight of structures can still be highlighted. Firstly, there cannot be a high-quality product, the weight of which is 30-40 kg. This means only one thing - steel with a thickness of 0.5-0.7 mm was used in the manufacture, which is a characteristic feature of the products of some Chinese companies.

The standard weight of an entrance door with a frame, in the manufacture of which metal complying with GOSTs was used, cannot be less than 55-60 kg. Moreover, when using steel with a thickness of 1.8-2.0 mm, which is usual for most of the most popular models on the market from serious manufacturers, the weight of the finished product is 70-80 kg. Of course, this figure also includes 5-6 stiffeners installed in such steel doors.

It should be noted that the mass of entrance doors belonging to the elite category can be up to 100-110 kg. It is the result of several factors. Firstly, steel with a thickness of 2-2.2 mm is used in the manufacture. Secondly, the number of stiffeners can reach 6, and for some models 8-10 pieces. Thirdly, in the design of the product, solid wood, forged elements are used, as well as the already mentioned inserts of glass, mirrors or stained-glass windows, which are of considerable weight.

Weight of fireproof, armored and insulated metal doors

Quite often, potential buyers ask themselves how much an entrance door should weigh, which has increased thermal insulation or fire-fighting characteristics. The answer to it can vary greatly, depending on the specific type of product and, just as important, its size.

For insulated doors, factors affecting the weighting of the structure are a higher consumption of heat-insulating material, the device of an additional element, which is a thermal break, as well as a more complex profile of the box and the fabric of the product, thanks to which a three-circuit sealing system is created. As a result, the insulated entrance structure may well weigh 110-120 kg, and often more.

Fireproof steel doors have even more serious parameters. This is due to an increase in the consumption of metal, the thickness of which may not be 2, but 3 or even more mm. In armored structures, this figure can reach 6 mm. In addition, in such products, additional protective parts and elements are provided, which also affects the increase in weight. As a result, the weight of fire-prevention structures ranges from 80 to 120 kg, and in the double-leaf version - up to 160-170 kg. The mass of armored products is practically unlimited and can be equal to 200 or 300 kg, often surpassing even these impressive figures.

When choosing a new door to an apartment as an entrance or interior door, any person pays attention to the quality of workmanship, material and appearance. However, in some cases, one of the most important selection criteria is the severity of the structure. There are several reasons why reliable information is needed about how much a metal door or a product made from other materials weighs.

Children and elderly people will not be able to open a heavy structure. There is also a high risk of serious injury when hitting a door with a large mass. In addition, one should take into account the need to create additional fasteners for products heavier than 60 kg.

What affects the weight of the product

The main elements that directly affect the final weight are the selected material, the available filling, as well as their thickness. In addition, the following elements affect the weight of an interior door or entrance structure:

• Main and additional fittings;
• Internal thermal insulation layer and its density;
• Sheathing elements;
• Main blade thickness;
• Box.

Also, when calculating the mass of a composite structure made with decorative inserts other than the main materials, it is important to take into account the difference in the density of materials and the dimensions of the elements. The thin steel sheet used for the lightest blades is 0.8 mm. The thickest sheet is made with dimensions of 4 mm.

To reduce the total weight and, at the same time, to give a significant strength to the product, stiffeners are placed inside, between the two main sheets. Between them, in most cases, to increase sound and thermal insulation, manufacturers put polystyrene or mineral wool.

At the present time, the lock mechanism significantly affects the weight of a metal door. In most cases, manufacturers equip canvases with a set of 2 locks, the nominal weight of each of which can reach 7 kg.

Iron products

It is rather difficult to name the exact weight of metal doors, since iron can have different thicknesses and workmanship. However, approximate figures can still be derived.

The design of the simplest standard products weighs in the range of 40-50 kg. The lightest are Chinese-made structures with powder spraying and a steel plate thickness not exceeding 2 mm. Such products have no special decorative elements, and their weight is about 40 kg.

The most acceptable weight for an entrance metal door, together with the frame, ranges from 60-70 kg. Such a structure often has a decorative veneer or laminate coating, or is finished with MDF panels. Products with high value natural solid wood elements usually weigh over 100 kg. When manufacturing high-strength doors with multilayer steel construction, the total weight of the door leaf is more than 150 kg.

It is important to remember how much the selected iron door actually weighs. Since, despite the high efficiency of heavy elements, there is a rather significant drawback in the issue of ensuring safety. Such products are not only inconvenient during installation, but also tend to deform during operation from their own gravity. Therefore, such input elements need additional care in the form of a systematic adjustment of the bearing loops and the position of the canvas itself.

The most massive products using steel are special-purpose doors, namely:

• Fire safety models;
• Armored systems;
• Products with improved anti-burglary characteristics.

Such structures can have a nominal weight of the order of 120-150 kg.

Interior doors

The severity of a structure made with plastic can be calculated from the ratio of weight to dimensions of the canvas. So, 1 square meter of the product contains 1.5 kg of material. In the case of using metal inserts inside the structure, the weight will already be 2.5 kg per 1 sq. M.

The weight of wood doors depends largely on the structure of the material used and the type of wood species. The mass of the material made of solid deciduous trees is more than 20 kg. for 1 sq.m. In the case of using light and soft, often coniferous types of wood, the nominal weight of a wooden product is reduced to 15 kg per 1 sq. M.

Using these numbers, it is easy to calculate the severity of an interior door of a deaf type of manufacture. So, taking into account the weight of all the accessories necessary for the product, including handles and locks, the approximate data will be as follows:

• Plastic construction about 5 kg;
• Glass about 20 kg;
• Wooden, depending on the breed, from 25 to 40 kg.

However, it should be remembered that the weight of a wooden door that has glass or plastic components can be strikingly different from a deaf type design. By the same principle, door elements differ, having different design solutions, but at the same time made of the same type of materials. So, a high sliding door, when manufactured using natural elements, will not be lighter than 100 kg.

A door made of MDF material can weigh no more than 10 kg, when it is made hollow or when using cardboard filling. In the case of filling the interpanel space to enhance the heat-insulating and sound-absorbing qualities with tempered glass, the weight of the product increases significantly.

The heaviest structures made with solid natural wood materials are oak doors. Their weight can significantly exceed the weight of a metal door. The use of such massive structures at home is justified only if it is necessary to give a respectable look and with the obligatory presence of large free space and strong walls. An alternative option, in which you can get the same effect, but with a much lighter construction, is to use lightweight products with decorative veneering.

The question "How much does an interior door weigh?" is one of the most important when choosing this interior element. Along with color, material, shape and other features, mass is of great importance. The features of the door frame, hinges and other accessories, which will ensure the durability of the structure and its aesthetic appearance, depend on this factor.

What determines the weight of the product?

The weight of an interior door directly depends on the quality of the material from which it is made. Factory models are manufactured in accordance with state standards and have typical indicators: size and weight.

Materials, in turn, have such a property as density. The specificity of the material from which the product is made directly affects how much the door weighs. Here are the densities of the most common materials:

A lot of different doors, their advantages and disadvantages

Each of the materials has its own advantages and disadvantages.

The plastic has unrivaled insulating properties. It retains heat well, cuts off odors and noises. Models made of this material are light in weight, they have a reduced risk of injury. Plus they are affordable. The main disadvantage of these models is that they are not environmentally friendly and even toxic. Therefore, they are not recommended to be installed in residential buildings. An exception may be products made of high-quality plastic, which are comparable in cost to wooden models.

An interior door with glass looks laconic and attractive. These models allow you to give the room airiness, the interior - lightness, let in a large amount of sunlight into the room. Modern tempered glass or triplex is characterized by high impact strength and safety. However, their price makes you think about the advisability of installing such a model.

Models made with wood processing products are considered worthy replacements for solid-state counterparts. They are more affordable, moisture and temperature resistant. In addition, the wood-shaving material weighs less in comparison with the solid wood. Finishing of fine wood veneer gives the product a respectable appearance.

The products of new technologies are alternative synthetic materials that cover the canvas to give not only external gloss, but also to increase significant consumer qualities. New generation materials include artificial veneer (laminate), nanoflex and eco-veneer. They are considered an example of environmental friendliness and are highly resistant to moisture and temperature extremes. The polymer coating provides less weight for the veneer door.

Models made of hardwood (hard) wood are considered an attribute of luxury. Their cost is really high, but it is offset by the benefits. These products are reliable, durable and very beautiful. However, wood can quickly lose its appearance due to a sharp temperature drop and high humidity in the room. In order to prevent a wooden door from deforming from adverse factors, it is covered with special moisture-resistant compounds. The mass of such products, depending on the type of wood, can reach up to 150 kg. This means that the load on the door hinges will be maximum; you will need especially strong hardware and a high-quality wooden frame.

In appearance, PVC models are practically indistinguishable from solid or veneered products. They are resistant to adverse external factors, aesthetic and practical to care for.

Factors affecting the mass of the interior product

Other factors also affect the weight of the door:

1. Blade dimensions (length, width and thickness). Models made of the same material, the same height and width, but differing in thickness by a few millimeters, will have a difference in weight of several kg (depending on the material);
2. Uniformity of the material. Products can be solid and glazed, made of the same material, or contain a combination of materials with different densities. All these nuances are reflected in the mass of products.
3. Its production technology:
   • The heaviest will be doors made of solid wood, whose weight can reach 140 kg.
   • Slightly lighter than paneled products. Veneer interior doors contain fragments of wood-based materials (chipboard, MDF). The upper part of such products may contain inserts in the form of panels, glass, or cellular cardboard. The severity of the model will depend on the quality of the insert. It ranges from 20-40 kg.
   • Panel products have a hollow structure. The cavities are usually filled with honeycomb-shaped cardboard inserts. These models are distinguished by their low weight - 10-15 kg.
4. The quality of the accessories used. Door handles, lock and other accessories add weight to the product in the direction of increasing.

Why do you need to know the weight of the door?

The weight of the canvas needs to be known for several reasons.

Firstly, this information is needed to select the correct door frame, if it is not included in the package. If a heavy piece of solid wood is hung on a MDF box, then such a structure will not serve for a long time.

Hinges are also selected according to the weight of the product. Doors of various designs have their own subtleties of location, attachment to the box.

Secondly, the weight of the door will allow the owners of the apartment to plan the correctness of its placement. Heavy items will be out of place in a nursery or bathroom. This will create an unsafe living environment and cause difficulties in operation.

To ensure reliable protection of housing from intruders, a metal door is most often used, it is distinguished by its reliability and durability. The weight of a metal door determines its resistance to mechanical burglary and susceptibility to deformation during operation.

All metal doors depend on the design and affect the degree of burglary resistance

Requirements for metal doors

To begin with, let's consider what the requirements are for an entrance door made of metal:

• Reliability... Protection of housing from mechanical burglary and penetration by opening the locks can only be guaranteed by a high-quality product. When choosing, it is important to consider not only the design and thickness of the steel sheets, but also the locking mechanism system.
• Heat and sound insulation... To preserve heat in the house, a heat-insulating layer must be placed between the metal sheets, which also serves as sound insulation.
• Durability... By installing a new metal door, residents are counting on its reliable long-term operation. Therefore, special attention should be paid to the weight of the steel structure and hinges, they must be designed with a safety margin. Otherwise, over time, there may be problems with opening / closing due to skew.

Strength and reliability are the main requirements for an entrance metal door

What components affect the weight of the structure

The main component that determines the weight of the product is the thickness of the metal sheets used. In general, the weight of the door is made up of the following factors:

• thickness of steel sheets;
• weight of the metal box;
• number of stiffeners;
• thermal insulation layer;
• sheathing;
• additional fittings.

Design features directly affect the weight of the door

Sheet steel used for the manufacture of metal doors is of two types: cold and hot rolled. Hot rolled steel is cheaper but corrosive. This alloy is designated 19903 in accordance with GOST. Cold rolled sheet (19904 according to GOST) is more expensive, resistant to humidity, temperature extremes, suitable for exterior doors of private houses or an entrance.

The thickness of a thin steel sheet is 0.8 mm, and a thick one is 4 mm. For the entrance door to the apartment, the optimal value should be at least 2 mm. And for reliable protection of a summer house or cottage, you should choose 4-millimeter sheets.

To reduce weight and impart greater rigidity to the structure, the ribs are made of rolled products with a complex profile that cannot be mechanically bent. The number of ribs is selected from the reliability / weight ratio. The minimum number of stiffening ribs, laid in the manufacture of the door - two vertically, one horizontally. But in order to provide protection against hacking, it is better to increase their number.

To give the structure reliability, metal doors are equipped with stiffeners, the number of which determines the weight of the product

For heat and sound insulation of housing, a special heat-insulating layer is placed between the steel sheets of the door structure. As a heater, polystyrene plates or mineral wool are usually used. To give an aesthetic look, steel sheets are sheathed with veneer, MDF or laminated panels. Each of these parts adds to the overall weight of the structure.

Modern door models, as a rule, combine several locks of different types, the weight of such a locking mechanism can reach 7 kg. Moreover, the more the finished product weighs, the more loops there will be. The standard entrance design is equipped with two hinges. For heavy specialized products, 3-4 loops are required.

How much does the finished product weigh?

So how much does a metal door weigh? The lightest are Chinese metal products, weighing about 40 kg, as a rule, powder coated with a sheet thickness of no more than 2 mm and do not have any additional linings. Such products are not able to provide reliable protection for an apartment. The optimal weight of a metal door for an apartment is 60-70 kg, such doors are most often covered with laminate, veneer or MDF panels. Structures finished in solid natural wood often weigh more than 100 kg.

The front door, covered with laminate or MDF panels, weighs about 70 kg

The weight of heavy-duty metal structures with a double or triple layer of steel can reach 150 kg or more.

Of course, such a door will provide the most reliable protection, but too massive structures can cause certain inconveniences during installation, moreover, heavy doors sag over time. Therefore, during long-term operation, it is necessary to regularly correct the position of the web by adjusting the loops.

When choosing a metal structure, one should focus not only on its weight, but also on the manufacturer. Firms that care about their reputation will not use low-grade raw materials and unnecessarily weight products, but will direct all efforts to the strength and reliability of the structure.
